GnuPG-bug-id: 7213
Backported-from-master: 690fd61a0c
This backport required to introduce the new tlv-parser.c file and
remove most source copied stuff from minip12.c. Thus the above
ChangeList is not fully correct.
* common/tlv-builder.c: New.
* common/tlv.c: Remove stuff only used by GnuPG 1.
(put_tlv_to_membuf, get_tlv_length): Move to ...
* common/tlv-builder.c: here.
* common/tlv.h (tlv_builder_t): New.
--
Such code should actually go into libksba and we will eventually do
that. However, for now it is easier to keep it here.

(cherry picked from commit 5ea878274e)
- Add coverity meta comment from
commit a95ddffdcd
* scd/iso7816.c (iso7816_select_path): Add arg top_fd.
* scd/app-nks.c (do_readkey): Adjust for this change
(select_ef_by_path: Ditto.
* common/tlv.h: Include membuf.h.

Including membuf.h is just for easier backporting. In 2.3 it is
actually required in tlv.h but in 2.2 we right now only use it
indirect.
We better do this once and for all instead of cluttering all future
commits with diffs of trailing white spaces. In the majority of cases
blank or single lines are affected and thus this change won't disturb
a git blame too much. For future commits the pre-commit scripts
checks that this won't happen again.
